Rapid biexciton state preparation in a quantum dot using on-off pulse-sequences
Dionisis Stefanatos, Emmanuel Paspalakis
We consider the problem of pulsed biexciton preparation in a quantum dot and show that a pulse-sequence with a simple on-off-on modulation can achieve complete preparation of the t…
Performance of superadiabatic stimulated Raman adiabatic passage in the presence of dissipation and Ornstein-Uhlenbeck dephasing
Kostas Blekos, Dionisis Stefanatos, Emmanuel Paspalakis
In this paper we evaluate the performance of two superadiabatic stimulated Raman adiabatic passage (STIRAP) protocols derived from Gaussian and sin-cos pulses, under dissipation an…
Dynamical blockade in a bosonic Josephson junction using optimal coupling
Dionisis Stefanatos, Emmanuel Paspalakis
In this article we use time-dependent Josephson coupling to enhance unconventional photon blockade in a system of two coupled nonlinear bosonic modes which are initially loaded wit…
Control of nonlinear optical phenomena and spatially structured optical effects in a four-level quantum system near a plasmonic nanostructure
Hamid Reza Hamedi, Vassilios Yannopapas, Emmanuel Paspalakis
We investigate the nonlinear optical response of a four-level double-V-type quantum system interacting with a pair of weak probe fields while located near a two-dimensional array o…
Off-axis optical vortices using double-Raman singlet and doublet light-matter schemes
Hamid Reza Hamedi, Julius Ruseckas, Emmanuel Paspalakis +1
We study the formation of off-axis optical vortices propagating inside a double-Raman gain atomic medium. The atoms interact with two weak probe fields as well as two strong pump b…
